HDPE给水管道的固定方式是怎么样的?

作者: admin    来源:http://www.laobingguandao.com  时间:2019-07-24    人气:
  HDPE给水管道是由塑料挤出机生产的特种聚乙烯材料制成,广泛应用于城市给水管网、灌溉引水工程和农业喷灌工程。
  HDPE water supply pipeline is made of special polyethylene material produced by plastic extruder. It is widely used in urban water supply network, irrigation diversion project and agricultural sprinkler irrigation project.
  PE到水管连接固定的方式怎么做是最好的:
  How to fix the connection between PE and water pipe is the best way to do it.
  1. PE水管焊接时,将两根管子轴线对齐,点焊固定两根管子的两端。PE对管道和法兰进行焊接时,应先将管道放入法兰内,点焊时用直尺找对,焊后找平。法兰两侧应焊接,内侧面不得凸现法兰密封面。
  1. When PE pipe is welded, the axes of two pipes are aligned and the ends of two pipes are fixed by spot welding. When PE welds pipes and flanges, the pipes should be put into flanges first. When spot welding, the pipes should be aligned with rulers and leveled after welding. The flange should be welded on both sides, and the flange sealing surface should not be protruded on the inner side.
  2、PE壁厚5mm或以上,应切割坡口,以保证焊接完全穿透。坡口成形可通过气焊或坡口加工进行切割,但应去除炉渣和氧化铁,切割面应垂直于管道中心线,以保证管道焊接的同心度。法兰应垂直于管的中心线,表面应相互平行,法兰垫片不应凸管,连接法兰的螺栓规格应与法兰,伸出螺母的螺丝的长度不应超过1/2直径的螺丝。
  2. PE wall thickness 5 mm or more should be cut groove to ensure complete penetration of welding. Groove forming can be cut by gas welding or groove processing, but slag and iron oxide should be removed, and the cutting surface should be perpendicular to the central line of pipeline to ensure the concentricity of pipeline welding. The flange should be perpendicular to the center line of the pipe, the surface should be parallel to each other, the flange gasket should not convex the pipe, the bolt specifications of the connecting flange should be flanged, and the length of the bolt extending the nut should not exceed 1/2 diameter of the bolt.

  3、当焊接到管道时,管道接口要清除锈迹、污垢和油脂。法兰垫片应按图纸和规范要求选用,冷水系统选用橡胶垫片应使用,热水系统选用石棉橡胶垫片应使用。
  3. When welding to the pipeline, the pipeline interface should remove rust, dirt and grease. Flange gaskets shall be selected according to drawings and specifications, rubber gaskets shall be used in cold water system and asbestos rubber gaskets shall be used in hot water system.
  因此,由于使用PE管热熔,热熔连接实现接口的集成和管道,并能有效地抵抗的压力环向应力和轴向应力,重金属和PE管道的影响不加盐稳定剂,材料无毒,不伸缩,不滋生细菌,桡骨的PE水管方法是需要注意的。
  Therefore, due to the use of PE pipe hot-melt, hot-melt connection to achieve interface integration and pipeline, and can effectively resist the pressure circumferential stress and axial stress, heavy metals and PE pipes are not affected by salt stabilizers, materials are non-toxic, non-telescopic, and do not breed bacteria, the PE pipe method of radius needs attention.
